第71期 New speech (Part I)14/11/2019

Have you ever wondered how humans developed to be the ruler of the Earth? Have you ever wondered how humans developed their technology by developing their brains? All answers are concentrated in this "A Brief History" series written by Yuval Noah Harari. There are in total of three books in this series and they are "Sapiens: A Brief History of the Mankind", "A Brief History of the Homo-Deus", and "A Brief History of Tomorrow". All these books are have been evaluated as recognition beyond times. So, have you been excited already? No? That right, because I literally haven't said anything about the book yet. But I can guarantee you that after my speech is finished, you will be looking at "A Brief History" series from a completely different perspective.

First of all, in "Sapiens: A Brief History of the Mankind", the author used detailed languages to described the origin of all subjects, where do they come from and what do they do. About 13.5 billion years ago, after the Big Bang, the substances, energy, and space built the current thing that we called- the universe. All the fundamental existence and rule of how they work in time and space, we called it- Physics.

Then after about three hundred thousand years, those fundamental existences and energy started forming complicated structures called- Atoms. The study combinations of atoms is what we called- Chemistry.

In the further step, the combinations of these atoms, which are molecules, keep combining each other to create the first type of organism- mono-cell. They split with trembling, keep copying and pasting themselves with exponential speed to form other organisms which are more complicated. The study of these organisms is what we called- Biology.

In the meantime, an insignificant planet called Earth was born. At that time, mountains could rise up for thousands of meters high and drop down in a few minutes. After the Earth cooled down, the ground, which is the crust of the Earth become harder, become stronger, become more appropriate for lives to live on. The study of the physical feathers on Earth, the life activities on Earth and the interactions between artificial objects and nature are what we called -Geography.

Briefly about forty-five thousand million years after the Earth was born, a kind of life form which just like other species, humans appeared. They invented rock axes, figured how to control fire, built up kingdoms and countries, issued money and cheques and even further, we invented the Voyager, we invented the Boeing 747-8, we invented the quantum computer and we invented the Hadron Collider. All the stories in this stream of humans are what we called- History.
